Actually we have fix shuttering for loft slab on7ft. Afetr the final decision of our client we have cancelled loft slab. Now should we pour half columns and then completed the whole columns upto heightft or we have to pour columns concrete at once?
It is better to place concrete of a column 12 ft height at once, but I am limited with 7 ft shuttering as source, I make 2nd placement by prociding:
--Rebar design no change
--1st and 2nd concrete placement no offset
--Interface clean and rough
Construction methodology is a function of resources and limitations with pouring columns. To my mind i would pour columns to full height, taking care to place and compact concrete properly and not over loading forms, i like to limit my placement rate to 1m head per hour.
The two solution are correct as a contractor you can choose the solution which save the money as consultant i will choose the second.
